Other influences are Celtic Faerie Wicca, which is shown in Rich Definition in the Design of House Ei. House Walker is what House Ei becomes when Yur-Ei is murdered by the High Council. House Walker has a Darker Motif, moving from Celtic Faerie Wicca into Dragon Wicca.

It is also of note that "Fire Walker" and "Firestone Possession" are not the same Transformation.

Firestone Possession is the Avatar Effect where touching one of the 16 Stones enslaves the Human and changes them on every level to become a Servant of that Stone in a way that alters their very Being.

Wind Walker is strong enough in her Magic to where the Avatar State doesn't take permenently, nor all the way. Her hair changes color to match the Stones' Aesthetic, as do her eyes, and her Skin to a lesser extent. She gains the power of that particular stone temporarily just like Rogue from the X-Men absorbs Mutant Powers temporarily by touch.

"Fire Walker", though, is a Rare Form that has Deus Ex Machina Powers and is used very infrequently when Wind Walker is truly backed into a corner with no way out, and is about to die. It is so powerful a form that it vaporized the 4 Planets of Old Akashmiran and the Star around which they held Orbit.

The People of Old Akashmiran escaped, due to the Old Magic that their Culture was steeped in, but suffered great loss. The 4 Kings of Old Akashmiran recognized Wind Walker's Power and bent the knee to her in fealty, starting her reign as Empress Wind Walker of New Akashmiran. It took 30 years and a severe overhaul of the Old Magic, with help from the Divine Realm of Domminna, to reforge the 4 Planets and their Star.

So, I really don't want to hear any confusion when it comes to Fire Walker and Firestone Possession.

There is no such animal as "Hate Walker" or "Peace Walker" and their won't be, because Fire Walker is a Special Technique that overwrites and overpowers everything to such an OP degree that it would very much unbalance the Story.

I was considering making the Stone Possession into a Mega-Man Type of Ability where Wind Walker could learn all the abilities of the 16 Stones by touch/osmosis, which would lead to her becoming a Circle Mage, but that is not high enough in difficulty for the definition of a Circle Mage.

The Circle Mage is Orbspace equivalent to the "Six Paths Sage Mode" in the Naruto Universe, and is one of the rarest and most difficult abilities to construct for good reasons. It wouldn't be rare or special at all if it was easy.

Wind Walker can do it, but she'll have at least as much difficulty in doing so as Madara Uchiha did.

The Original Circle Mage was Circle Oaennar, was born on the Planet Oaenalia of Peacestone, and resides with the Deities in Domminna as their Chief.
